iPhone: Fake phone call escapes are nothing new, but Fake-A-Call has a certain style when it comes to deliberately faking an important call. The screen looks real, the caller ID is custom, and there's even a fake answer recording.

Whenever you think it's [appropriate to create a fake call](http://lifehacker.com/5754482/when-is-it-appropriate-to-fake-a-phone-call), Fake-A-Call lets you set up notably rich scenarios. Scripts are included in the app, so you can correspond with the pre-recorded voice on the other end. The buttons that show up on the fake call screen? They actually work. Press "Mute," tell your unwanted conversationalist that you "need to take this," then turn on speakerphone as you're walking away, for rather stunning verisimilitude. It's a free app with advertising in the App Store; the ad-free version is 99 cents.
